The smartphone is likely to come with double lens camera, 2,900 mAh battery

HTC One+

There have been lots of rumors regarding the upcoming sequel to the HTC One and some of them seem to be pretty accurate. We reported yesterday on some preliminary specs of the so-called HTC M8, which is the codename for the HTC One successor.

Today, new details on the HTC M8 have just surface, this time from a completely different source. Popular XDA ROM developer Mike1986 who regularly obtains leaked HTC software builds has it from sources close to the matter that the next flagship smartphone to be released by the Taiwanese handset maker will be called HTC One+.

HTC One+ will ship with Android 4.4 KitKat operating system and HTC Sense 6.0 on top. These are major software upgrades in comparison with the rest of HTC smartphones currently available on the market.

However, by the time the HTC One+ goes on sale, most of HTC's high-end smartphones might receive the highly anticipated Android 4.4 KitKat update.

Furthermore, HTC is said to replace the Snapdragon 800 chipset inside the current One model with the superior Qualcomm Snapdragon 805 chipset, which will be complemented by 2GB of LPDDR3 of RAM.

However, according to Mike1986 there might be a small issue with the drivers development from Qualcomm's part, but let's hope these issues will be ironed out by the time the HTC One+ goes official.

It is also worth mentioning the One+ will come with an enhance UltraPixel camera, which will feature a 6- or 8-megapixel module. The camera will pack HTC ImageChip 3 technology and also double lens (for low and high lighting).

The One+ will also sport a large 5-inch full HD capacitive touchscreen display with Corning Gorilla Glass 3 coating and a much better 2,900 mAh Li-Ion battery (as opposed to the 2,300 mAh battery).

More importantly, the HTC One+ will come packed with microSD card slot for memory expansion. It looks like the company has taken to heart all the negative feedback coming from the fans who were complaining about the lack of this feature.

Last but not least, the One+ is said to lack any capacitive buttons, so we can say goodbye to the common "Home" and "Back" keys.

Now we can only wait and see how many of these specs are accurate and which will be skipped by the Taiwanese company.

HTC is expected reveal its next flagship smartphone next month at Mobile World Congress (MWC) 2013, but more unofficial info might continue to surface by then so stay tuned.
